feat(home-assistant): add alexa_media_player custom component

Package the Alexa Media Player HACS component declaratively (v5.15.7),
so HA can drive the Echo devices (TTS/announce, media, sensors). Needs
dictor 0.1.12 (absent from nixpkgs) and an alexapy 1.29.22 -> 1.29.25
bump to satisfy the manifest's exact requirement pins; both build
against HA's interpreter. Config-flow based: add via the HA UI and sign
in with the Amazon account after rebuild.

+# Alexa Media Player Integration — Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Package the `alexa_media_player` HACS component declaratively on jupiter's Home Assistant so HA can drive the household Echo devices (TTS/announce, media, sensors).
+
+**Architecture:** Add one `buildHomeAssistantComponent` entry to `services.home-assistant.customComponents` (same pattern as the existing `ha-sourdough`). The component has real Python deps, so the module's `let` block also defines two supporting derivations built against HA's own interpreter: a new `dictor` package and an `alexapy` version bump. No HACS runtime, no YAML config — the integration is added through the HA UI after the rebuild.
+
+**Tech Stack:** NixOS, `pkgs.buildHomeAssistantComponent`, `buildPythonPackage`, `fetchFromGitHub`/`fetchFromGitLab`/`fetchPypi`.
+
+## Global Constraints
+
+- Target machine: **jupiter** only. All edits live in `modules/environments/home-assistant/default.nix`.
+- Python dep derivations MUST build against Home Assistant's interpreter set — `pkgs.home-assistant.python3Packages` — the same set `buildHomeAssistantComponent` uses. Do not use top-level `pkgs.python3Packages`.
+- Manifest requirements are enforced at build time by `manifestCheckPhase` and again by HA at runtime. Every requirement must resolve to an installed dist satisfying its specifier. Exact pins (verbatim from `alexa_media_player` v5.15.7 `manifest.json`):
+  - `alexapy==1.29.25`
+  - `dictor>=0.1.12,<0.2`
+  - `wrapt>=1.14.0`  (nixpkgs 1.17.2 — already satisfied)
+  - `packaging>=20.3`  (nixpkgs 26.1 — already satisfied)
+- Pinned artifacts (all three hashes verified to build during planning):
+
+  | Artifact           | Fetcher          | Ref / version | Hash                                              |

+
+## File Structure
+
+Single file touched: `modules/environments/home-assistant/default.nix`.
+- Its `let` block gains `haPython`, `dictor`, and `alexapy` bindings.
+- Its `services.home-assistant.customComponents` list gains a second entry (`alexa_media`) alongside the existing `sourdough` entry.
+
+No new files. The two supporting derivations are small and specific to this component, so they live inline in the module's `let` block next to their only consumer (files that change together live together).
+
+---
+
+### Task 1: Package `alexa_media_player` with its Python dependencies
+
+**Files:**
+- Modify: `modules/environments/home-assistant/default.nix` (the `let` block, currently lines 9-12; and the `customComponents` list, currently lines 29-41)
+
+**Interfaces:**
+- Consumes: `pkgs.home-assistant.python3Packages` (HA interpreter set), `pkgs.buildHomeAssistantComponent`, `pkgs.fetchFromGitHub`, `pkgs.fetchFromGitLab`.
+- Produces: a second `customComponents` entry with `domain = "alexa_media"`. No other module consumes these `let` bindings.
+
+- [ ] **Step 1: Add the supporting derivations to the `let` block**
+
+Edit the `let` block so it reads exactly:
+
+```nix
+let
+  cfg = config.my.profiles.home-assistant;
+  hostName = config.networking.hostName;
+
+  # Python deps for the alexa_media_player custom component (Task: Alexa).
+  # Built against Home Assistant's own interpreter — the same set
+  # buildHomeAssistantComponent uses — so HA's build-time and runtime
+  # manifest-requirement checks are satisfied.
+  haPython = pkgs.home-assistant.python3Packages;
+
+  # dictor is not in nixpkgs; alexa_media_player needs dictor>=0.1.12,<0.2.
+  # Pure-Python, no runtime deps, legacy setup.py.
+  dictor = haPython.buildPythonPackage {
+    pname = "dictor";
+    version = "0.1.12";
+    format = "setuptools";
+    src = haPython.fetchPypi {
+      pname = "dictor";
+      version = "0.1.12";
+      hash = "sha256-bbSDda4eU9ye2EToWzj04/v79qTmC+yjd1Fa0URTuRs=";
+    };
+    build-system = [ haPython.setuptools ];
+    doCheck = false;
+    pythonImportsCheck = [ "dictor" ];
+  };
+
+  # nixpkgs ships alexapy 1.29.22; the manifest pins ==1.29.25. Patch bump.
+  # nixpkgs fetches alexapy from GitLab (keatontaylor/alexapy), tag v<version>.
+  alexapy = haPython.alexapy.overridePythonAttrs (old: {
+    version = "1.29.25";
+    src = pkgs.fetchFromGitLab {
+      owner = "keatontaylor";
+      repo = "alexapy";
+      tag = "v1.29.25";
+      hash = "sha256-P/hvgqZVaBJF5dbmHrDjQMC+pwV3EEhKyFIS5KmhgD4=";
+    };
+  });
+in
+```
+
+- [ ] **Step 2: Add the `alexa_media` entry to `customComponents`**
+
+In `services.home-assistant.customComponents`, immediately after the closing `)` of the existing `sourdough` entry (current line 40) and before the list's closing `]` (current line 41), add:
+
+```nix
+        (pkgs.buildHomeAssistantComponent {
+          owner = "Alandtse";
+          domain = "alexa_media";
+          version = "5.15.7";
+          src = pkgs.fetchFromGitHub {
+            owner = "Alandtse";
+            repo = "alexa_media_player";
+            rev = "v5.15.7";
+            hash = "sha256-1rcZVSX1xA1Lc4qSu39MOitVEciZFhoPQy2y5+PpoAI=";
+          };
+          # Every manifest requirement must be importable at a satisfying
+          # version or manifestCheckPhase fails the build.
+          dependencies = [
+            alexapy
+            dictor
+            haPython.wrapt
+            haPython.packaging
+          ];
+        })
+```
+
+- [ ] **Step 3: Format the file**
+
+Run: `nixfmt-rfc-style modules/environments/home-assistant/default.nix`
+Expected: exits 0, no diff surprises (re-read the file if unsure).
+
+- [ ] **Step 4: Build the component in isolation first (fast feedback)**
+
+This is the real test: it runs `manifestCheckPhase`, which fails loudly if any of the four requirements is unmet. It was verified to succeed during planning.
+
+Run:
+```bash
+nix build --impure --no-link --print-out-paths --expr '
+  let
+    pkgs = (builtins.getFlake (toString ./.)).nixosConfigurations.jupiter.pkgs;
+    py = pkgs.home-assistant.python3Packages;
+    dictor = py.buildPythonPackage {
+      pname = "dictor"; version = "0.1.12"; format = "setuptools";
+      src = py.fetchPypi { pname = "dictor"; version = "0.1.12"; hash = "sha256-bbSDda4eU9ye2EToWzj04/v79qTmC+yjd1Fa0URTuRs="; };
+      build-system = [ py.setuptools ]; doCheck = false; pythonImportsCheck = [ "dictor" ];
+    };
+    alexapy = py.alexapy.overridePythonAttrs (old: {
+      version = "1.29.25";
+      src = pkgs.fetchFromGitLab { owner = "keatontaylor"; repo = "alexapy"; tag = "v1.29.25"; hash = "sha256-P/hvgqZVaBJF5dbmHrDjQMC+pwV3EEhKyFIS5KmhgD4="; };
+    });
+  in pkgs.buildHomeAssistantComponent {
+    owner = "Alandtse"; domain = "alexa_media"; version = "5.15.7";
+    src = pkgs.fetchFromGitHub { owner = "Alandtse"; repo = "alexa_media_player"; rev = "v5.15.7"; hash = "sha256-1rcZVSX1xA1Lc4qSu39MOitVEciZFhoPQy2y5+PpoAI="; };
+    dependencies = [ alexapy dictor py.wrapt py.packaging ];
+  }'
+```
+Expected: prints a `/nix/store/...-Alandtse-alexa_media-5.15.7` path, exit 0. If it fails with `<pkg><specifier> not satisfied by version ...`, a dependency version drifted — re-check the manifest pin against the provided dep.
+
+- [ ] **Step 5: Build the whole jupiter system (integration gate)**
+
+Run: `nix build '.#nixosConfigurations.jupiter.config.system.build.toplevel'`
+Expected: builds to completion, exit 0. This confirms the module edits evaluate and the component is wired into HA's package.
+
+- [ ] **Step 6: Commit**
+
+```bash
+git add modules/environments/home-assistant/default.nix
+git commit -m "$(cat <<'EOF'
+feat(home-assistant): add alexa_media_player custom component
+
+Package the Alexa Media Player HACS component declaratively (v5.15.7),

+
+## Post-implementation (manual, by the user — not an automatable step)
+
+After `sudo nixos-rebuild switch --flake '.#jupiter'`:
+1. Settings → Devices & Services → Add Integration → **Alexa Media Player**.
+2. Sign in with the Amazon account; complete any 2FA / app-password prompt in the UI flow.
+3. Confirm media_player entities and sensors appear; test a TTS/announce service call to an Echo.
+
+## Self-Review
+
+- **Spec coverage:** goal (alexa_media_player packaging) → Task 1; alexapy bump → Step 1; dictor packaging → Step 1; component entry → Step 2; wrapt/packaging already-satisfied → included as deps in Step 2; build-time manifest check → Steps 4-5; runtime config-flow → Post-implementation. Deferred Alexa→HA scope: intentionally absent. No gaps.
+- **Placeholder scan:** none — every step has concrete code/commands and the verified hashes.
+- **Type/name consistency:** `haPython`, `dictor`, `alexapy` defined in Step 1 and referenced by those exact names in Step 2; domain `alexa_media` consistent throughout; hashes identical across plan, spec, and the verified build.

+# Amazon Alexa integration for Home Assistant (jupiter) — design
+
+**Date:** 2026-07-29
+**Machine:** jupiter
+**Status:** approved, ready for implementation plan
+
+## Goal
+
+Let Home Assistant control and read the household Amazon Echo devices via the
+unofficial [`alexa_media_player`](https://github.com/Alandtse/alexa_media_player)
+integration: text-to-speech / announcements, media control, and per-device
+sensors (last-called device, next alarm/timer, DND state, etc.).
+
+This uses the user's Amazon account through an unofficial API. It is a
+config-flow integration: after the rebuild it is added through the HA UI, not
+via YAML.
+
+## Non-goals (deferred)
+
+Alexa → HA voice control ("Alexa, turn on the light") is **out of scope**. It
+would need either `emulated_hue` bound to port 80 on the LAN, or a public HTTPS
+endpoint plus the AWS-Lambda Smart Home Skill. The user chose to decide on that
+later. Nothing in this change touches the firewall, port 80, systemd unit
+capabilities, or network exposure.
+
+## Approach
+
+Package the integration declaratively, following the existing `ha-sourdough`
+pattern in `modules/environments/home-assistant/default.nix` (a
+`buildHomeAssistantComponent` entry in `services.home-assistant.customComponents`).
+No HACS runtime.
+
+Unlike sourdough, `alexa_media_player` has real Python dependencies. Its
+`manifest.json` (v5.15.7) declares:
+
+```
+alexapy==1.29.25
+packaging>=20.3
+wrapt>=1.14.0
+dictor>=0.1.12,<0.2
+```
+
+`buildHomeAssistantComponent` runs `manifestCheckPhase` at build time
+(`check_manifest.py`): every requirement must resolve to an installed
+distribution **whose version satisfies the specifier**, or the build fails.
+Home Assistant repeats this check at runtime. Therefore each requirement must be
+satisfied exactly — the exact `==1.29.25` pin in particular.
+
+Dependency status in the pinned nixpkgs (`nixos-25.11`):
+
+| Requirement            | nixpkgs today | Action                                  |
+| ---------------------- | ------------- | --------------------------------------- |
+| `alexapy==1.29.25`     | 1.29.22       | **Bump** to 1.29.25 via override        |
+| `dictor>=0.1.12,<0.2`  | *absent*      | **Package** dictor 0.1.12 (new)         |
+| `wrapt>=1.14.0`        | 1.17.2        | none — already satisfied                |
+| `packaging>=20.3`      | 26.1          | none — already satisfied                |
+
+`authcaptureproxy` (in nixpkgs at 1.3.7) is a transitive dependency of
+`alexapy`, not listed in the manifest, so it needs no direct handling.
+
+## Components
+
+All changes live in `modules/environments/home-assistant/default.nix` (plus the
+hashes below). Three small pieces, wired together in the module's `let` block:
+
+### 1. `dictor` package (new)
+
+Not in nixpkgs. Pure-Python, no runtime dependencies (`requires_dist: null`),
+ships a `setup.py`. A minimal `pkgs.python3Packages.buildPythonPackage`:
+
+- pname `dictor`, version `0.1.12`
+- `src = fetchPypi { pname = "dictor"; version = "0.1.12"; hash = "sha256-bbSDda4eU9ye2EToWzj04/v79qTmC+yjd1Fa0URTuRs="; }`
+- setuptools format (legacy `setup.py`); `build-system = [ setuptools ]`
+- `doCheck = false` (no meaningful test suite); `pythonImportsCheck = [ "dictor" ]`
+
+Build against the HA Python set so the version lands in HA's venv — i.e. use
+`config.services.home-assistant.package.python.pkgs` (the same interpreter the
+component check and HA runtime use), not the top-level `pkgs.python3Packages`.
+
+### 2. `alexapy` 1.29.25 (override)
+
+nixpkgs `alexapy` is fetched from **GitLab** (`keatontaylor/alexapy`, tag
+`v<version>`), not PyPI. Override just the version + src via
+`overridePythonAttrs`, reusing the existing build-system and dependency list:
+
+- `version = "1.29.25"`
+- `src = fetchFromGitLab { owner = "keatontaylor"; repo = "alexapy"; tag = "v1.29.25"; hash = "sha256-P/hvgqZVaBJF5dbmHrDjQMC+pwV3EEhKyFIS5KmhgD4="; }`
+
+This is a patch bump (1.29.22 → 1.29.25); the dependency set is expected to be
+unchanged. Override the HA-Python-set `alexapy` so it shares the interpreter
+with dictor and the component.
+
+### 3. `alexa_media_player` component (new `customComponents` entry)
+
+```
+buildHomeAssistantComponent {
+  owner = "Alandtse";
+  domain = "alexa_media";
+  version = "5.15.7";
+  src = fetchFromGitHub {
+    owner = "Alandtse";
+    repo  = "alexa_media_player";
+    rev   = "v5.15.7";
+    hash  = "sha256-1rcZVSX1xA1Lc4qSu39MOitVEciZFhoPQy2y5+PpoAI=";
+  };
+  dependencies = [ alexapy' dictor' wrapt packaging ];  # HA-python-set packages
+}
+```
+
+`dependencies` must make every manifest requirement importable at the required
+version for `manifestCheckPhase` to pass. Include all four (the two custom ones
+plus `wrapt` and `packaging` from the HA Python set) to be explicit.
+
+## Data flow
+
+1. `nixos-rebuild switch` builds the component; `manifestCheckPhase` validates
+   the four requirements against the provided `dependencies`.
+2. HA starts; the custom component is present but not configured.
+3. User adds **Alexa Media Player** in Settings → Devices & Services, signs in
+   with the Amazon account (email/password; 2FA or app-password handled in the
+   UI flow at runtime).
+4. HA creates media_player entities and per-device sensors; TTS/announce
+   services become available for automations.
+
+## Error handling / risks
+
+- **Version-pin drift.** If a future `alexa_media_player` bump changes the
+  `alexapy==` pin, `alexapy` must be re-bumped in lockstep, or the build fails
+  loudly at `manifestCheckPhase` (fail-safe, not silent).
+- **Amazon login fragility.** The unofficial API can break on Amazon's side
+  (captcha/2FA changes). This is a runtime concern, independent of packaging;
+  not addressed here.
+- **`dictor` upper bound `<0.2`.** 0.1.12 is the current release and satisfies
+  it. If nixpkgs later gains a `dictor` ≥ 0.2, prefer our pinned 0.1.12 for
+  this component.
+
+## Verification
+
+- `nix build '.#nixosConfigurations.jupiter.config.system.build.toplevel'`
+  succeeds — this exercises the build-time manifest-requirements check for all
+  three new/overridden derivations.
+- `nixfmt-rfc-style` clean on the edited module.
+- Post-deploy (manual, by the user): the integration appears under Add
+  Integration, and a TTS/announce call reaches an Echo.
